Question

Carlos plays an arcade game. The scatter plot shows his score and the number of minutes

he plays. A good line of fit is drawn through the points (6, 50) and (12, 80).
What is the slope of the line of fit?
m =?

Answer 1

The slope of this line (m) is 5

Explanation:

Slope is the change in y over the change in x.

The y values are 80 and 50 (6,50) (12,80) You find the change by subtracting these values

80 -50 = 30

The x values are 12 and 6 (6,50) (12,80) You find he change by subtracting these values.

12 - 6 = 6

`(30)/(6)` this reduces to 5
